Abstract (en)
[origin: WO9924446A1] A class of metallocenes of formula (I): (ZR<1>m)n(Cp)(A)rMLpL'q (I) wherein (ZR<1>m)n is a divalent group bridging Cp and A, Cp is a heterocyclic cyclopentadienyl group of formula (II) or (II'), wherein one of X or Y is a single bond, the other being an heteroatom; R<2> and R<3> are hydrogen, halogen or a hydrocarbon radical, optionally containing heteroatoms; R<4> is halogen or an hydrocarbon radical, optionally containing heteroatoms; the group A is a cyclopentadienyl derivative or is equal to Cp; M is Ti, Zr or Hf; m is 1 or 2; n ranges from 0 to 4; r is 0 or 1; p and q range from 0 to 3; and a ranges from 0 to 4. Moreover, are disclosed catalyst systems containing these metallocenes, useful in the polymerization of olefins.
